Charles Widmore - (Don't know the actors name) but when Kimmel asked him a question he responded (I don't know if Widmore was a good or bad guy.) Yeah, they had it all planned out..........
This just in

irectors give actors general directions for them to take their characters. They don't always spell everything out for them. Especially on a show built around mystery, where actors don't know how everything will play out. That way, they can't spoil anything when interviewed in real life. If that's concrete proof for you that the "writers had no clue where they were going", then that's up to you.
Terry O'Quinn also said on Kimmel that he played Season 5 without even knowing that his character was MIB. He was told to play a more confident Locke.Apart from that and Smoov's post, you can make a case for Widmore being good, or at least, doing whatever means necessary to reach what would have been a "good" result from his perspective. I am sure that Widmore considers himself good, so that comment from the actor who played him makes sense. Most of the other characters walked the good/evil line throughout the 6 seasons also, it was one of the shows themes.
